Dynamite Friction 4502-02028 Disc Brake Kit - Rear

DFC GEOSPEC Brake Kit for Porsche 911

DFC Friction part number 4502-02028 is a complete disc brake kit built for select Porsche 911 rear applications. It combines GEOSPEC coated rotors with 5000 Advanced Brake Pads for a direct-service brake replacement focused on OE-style fitment, corrosion resistance, and consistent pedal response.

The DFC GEOSPEC Rotors with 5000 Advanced Brake Pads line is engineered as a matched brake service kit, giving Porsche 911 owners a rotor-and-pad package from one source. For rear brake service on classic 911 models, this kit simplifies parts selection while keeping the components aligned to the vehicle’s original braking requirements.

• Complete disc brake kit with rotors and pads
• GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• Dry-processed, dry-shipped rotors ready for installation
• G3000/G11H18 cast iron rotor construction
• Non-directional rotor finish for even pad bed-in and smoother braking
• 5000 Advanced Brake Pads are post-cured and scorched for stable friction performance
• Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control
• Part number 4502-02028

This brake kit uses DFC’s GEOSPEC rotor coating to help resist rust while avoiding the extra cleaning step common with oil-coated rotors. The pads are prepared to reduce initial break-in time and deliver more consistent stopping response from the first stop. For Porsche 911 rear brake service, 4502-02028 provides a matched replacement solution for vehicles that need rotor and pad renewal together.

• Rear brake noise, vibration, or harshness during braking
• Rust or corrosion on existing rear rotors
• Uneven braking feel from worn rotor surfaces
• Extended stopping distance caused by worn pads
• Brake service on a Porsche 911 rear axle with matched components

Before ordering, verify rear axle configuration and caliper notes against the vehicle. Rotor coating is designed to be swept away by the brake pads during normal use, and the non-directional finish supports a more even bed-in process. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

DFC states that each rotor is machined to tight tolerances, inspected for balance where applicable, and checked against critical dimensions to meet OE specifications. The rotors include a 12-month warranty against defects in material and workmanship.
